You can use a Change node to move it into msg.payload.

There’s a great page in the docs ([Working with messages : Node-RED](https://nodered.org/docs/user-guide/messages)) that will explain how to use the debug panel to find the right path to any data item.

Pay particular attention to the part about the buttons that appear under your mouse pointer when you over hover a debug message property in the sidebar.

Next is ok! Thanks.

msg.payload = msg.payload[0].run  
return msg;

That would be more efficient in a Change node.  
Move msg.payload[0].run To msg.payload
